This is still present on the development branch (6.0).

I suspect the problem is that calling uimenu() to add the submenu invokes extra code that checks whether there is an existing menu, etc., and makes changes to the menu.  Then, when you delete the submenu, it just deletes the actual graphics object.  There probably needs to be destructor code written for the submenu that is called automatically by delete() to freshen the parent uimenu.

This issue is still present in Octave 4.2.0.

Confirmed, the context menu still thinks it has a submenu, although no menu shows up when it is selected and/or clicked.

After removing a submenu from a uicontextmenu, there are still  some remaining effects from that submenu:

  • the context menu still displays 'Menu 1  >' instead of 'Menu 1'
  • the uimenu callback is executed when the mouse pointer is over the label instead of only when a click is performed.

F=figure;
H=uicontextmenu(F);
set(F,'uicontextmenu',H);
U=uimenu('parent',H,'Label','Menu 1','callback','disp(''clbk'')');
uimenu('parent',U,'Label','temporary');
delete(get(U,'children'))
